I found this slideshow by the legendary Ocramius (Marco Pivetta). It has all aspects of setting up and using Doctrine 2 (which is fantastic btw, I’ve been using it for a while now) and makes for a nice little introductory tutorial, or, if you are an accomplished PHP developer, a nifty little quick install and go reference!
Anyway, I quite liked it and thought if any of you haven’t tried out the power of Doctrine, go try it now! Go kid go! 😀

(Use the arrow keys to change slides btw (nice little retro touch there 🙂 ))
